RD52.1-4B-018-D-LV-FW

The RD52.1-4B-018-D-LV-FW from Bosch Rexroth Indramat is a premium member of the RD 500 Drive Controllers series, engineered to precisely control the speed, acceleration, and overall operation of both synchronous and induction motors in complex industrial servo systems. Boasting a Nominal Connecting Voltage of 3 × AC 380–480 V and a Rated Power of 18.5 kW, this modular converter adapts to demanding applications such as food production machinery and automated material handling. Its primary function is to deliver reliable motor control in real time, ensuring smooth startup, dynamic response, and consistent performance across varied load conditions.

At the core of the RD52.1-4B-018-D-LV-FW lies its advanced Cooling Mode via a plug-through cooler, which dissipates heat efficiently without the need for complex external cooling loops. The drive comes as a Converter with a built-in brake chopper, integrating braking functionality to manage rapid deceleration sequences and protect system components. The device operates on a rated input current of 30 A and supports output frequencies from 0 up to 500 Hz, offering fine-grained motor speed control. An integrated signal processor enables real-time handling of high-performance tasks, while peer-to-peer coupling ensures seamless communication when linked with other drives in the same series.

Designed for robust industrial environments, this controller conforms to the A1 radio interference level standard and requires a 3K3 environmental class for optimum operation. It can be installed in ambient temperatures up to 45 °C and features a user-friendly operator panel with a clear display and pressure-sensitive keys for straightforward configuration and monitoring. The RS52.1-4B-018-D-LV-FW’s durable construction and global availability—with a one-year warranty—make it an ideal choice for manufacturers seeking enhanced efficiency, reduced downtime, and precise motor control in high-demand industrial applications.
